✦ Synopsis

Ž . Ž .

Ž . An overview of the formation of reconstructed facets on vicinal surfaces of Si 111 , Si 100 and Si 110 is given, which Ž . have been observed by using scanning tunneling microscopy STM . Most of the samples have been prepared by mechanical grinding, subsequent chemical etching leading to concave-shaped surfaces and by in situ treatment of high-index Si wafers. The orientation of the experimentally observed facets are represented in a stereographic projection, which allows the recognition of more general trends in facet formation. Moreover, it provides information on the availability of unit cells in a wide range of sizes and may therefore become important for the growth of self-organized surface structures. q 2000 Published by Elsevier Science B.V.
